Quick test of a tiny QEV cannon firing air at 12atm, viewed through a Schlieren setup (no razor blade). Edited from to 1/4th normal speed. I didn't quite understood the need for a razor blade but without one I still see the flow of air. For me, the razor blade just makes the dot of light smaller(?) If anyone can clarify me what the razor blade really does and where it should be placed (in the source of light or in the camera) I'd really appreciate. Also important to note that this is AWESOME to look with the naked eye but almost the dimmest light can blind you. I covered a tiny LED torch with aluminum foil and punctured a hole with a sewing needle, on the side! so that the LED doesn't bright directly through the hole. Take care with the eyes!!

I've been traveling to remote areas in Japan over the last 2 years to explore longevity hotspots and meet 'red zone rebels' – people who are defying the odds and living with independence, dignity, and freedom while showing few signs of dementia. I'm sharing their stories and uncovering the common patterns that make these communities thrive. https://www.nevertoolateacademy.com/post/haiku-aging-and-the-aha-moment About me: I’m Lowell Sheppard, 71, sailor, author, and Fellow of the Royal Geographical Society. I’m the Founder of the Never Too Late Academy and Special Advisor to IAFOR. Through Japan Solo Field Notes, I explore aging, place, and community across Japan. #Japan #Longevity #HealthyAging

Oggi è il centesimo giorno da quando abbiamo iniziato a fare i reel. Siamo partiti da Lignano Sabbiadoro, in Friuli, e in 100 giorni (non consecutivi) siamo giunti qui, al “punto di partenza”. Fa ridere dirlo perché in realtà già in questo tragitto tutto è cambiato, noi siamo cambiati, la barca è cambiata. Mi domando cosa accadrà all’arrivo in Martinica. Oggi è il centesimo giorno e volevamo celebrarlo con un gran video in pompa magna. Invece abbiamo pulito la barca a fondo, fatto un pezzo di spesa, fatto la lavatrice e poco altro. Un giorno ordinario insomma. In questa vita non ordinaria ✨
